I was wondering about a couple of things. We always hear that exercise and diet is the way to weight loss and physical fitness. Which I don't doubt in any way. I was just wondering since Cardio and Weight Training are the two componets needed for weight loss and since we need a deficit in calories to lose weight (fat hopefully) what does the body use to repair the muscles that are broken down during exercise if it dosen't have enough nutrition already? Of course I'm not talking about high intensity body builder no pain no gain type of workout but mainly the heart muscle during cardio type of exercise. I am a 47 yr old male considerably overweight and have a family history of heart issues (mostly in their 60's).
Also.. we hear that all that extra weight is putting a strain on your heart, it has to work harder. Why?? other than the obvious like moving 200 lbs requires x amount of energy as opposed to 150 lbs for the same distance.(irrelevant to a degree once we are in the water) Or is their mechanical reasons like the fat putting actual pressure on the heart muscle in it's cavity? Is their extra miles of cappilaries to pump blood through on a fat person as opposed to a thin person? And if so do these some how go away when we lose weight??
I guess what I'm asking is what is the actual process that makes that strain on the heart?
